The invention discloses a self-locking mechanism of an intelligent low-voltage switchgear cabinet. The self-locking mechanism comprises a cabinet body, a left cabinet door and a right cabinet door. A guide rail is fixedly connected to the inner side of the left cabinet door. The guide rail is provided with a pull rod in a sliding fit manner. A lock block is fixedly connected to the rear end of the guide rail, and an electromagnet is arranged. A rotation block is rotationally arranged on the inner side of the right cabinet door, a lock groove is formed in the bottom of the front end of the rotation block, and a connecting rod is hinged between the middle of the rotation block and the rear end of the pull rod. A left proximity switch is arranged on the inner side of the left cabinet door, and a right proximity switch is arranged on the inner side of the right cabinet door. A left electromagnet is arranged on the inner side of the part, in the cabinet body, of the left cabinet door, and a right electromagnet is arranged on the inner side of the part, in the cabinet body, of the right cabinet door. A left extension rod is fixedly connected to the inner side of the left cabinet door, and a right extension rod is fixedly connected to the inner side of the right cabinet door. On one hand, the left proximity switch and the right proximity switch are electrically connected with the electromagnet through a delay circuit; and on the other hand, the left proximity switch is electrically connected with the left electromagnet, and the right proximity switch is electrically connected with the right electromagnet The self-locking mechanism is simple in structure, the unlocked cabinet doors can be closed in time and locked, and safety of elements in the cabinet body and the surrounding environment is guaranteed.
Description
technical field [0001] The invention relates to the field of intelligent low-voltage switchgear, in particular to a self-locking mechanism of the intelligent low-voltage switchgear. Background technique [0002] Intelligent low-voltage switchgear is characterized by high performance, high reliability, certain self-diagnosis and automatic control performance, and network communication capabilities, and is widely used in the field of low-voltage power distribution. [0003] The staff opens the cabinet door to install and connect the internal components of the cabinet. After the operation is completed, if the staff forgets to lock the cabinet door due to negligence and leaves the scene quickly, the cabinet door will be closed. It will always be open and cannot be closed in time. The components inside the cabinet are easily damaged or lost due to exposure, and will also adversely affect the surrounding production and life. Contents of the invention [0004] The object of the ...
